REGULATING AND REVERSING APPARATUS.

Specification of Letters Patent.

Patented Apr. 26, 1910.

Application filed February 3, 1910. Serial No. 541,905.

To all whom it may concern:

Be it known that I, HEINRICH Korrnn, a subject of the German Emperor,residing at Bruchhausen, in the Empire of Germany and State of RhenishPrussia, have invented new and useful Improvements Relating toRegulating and Reversing Apparatus.

.My invention relates to regulating and reversing apparatus forregenerating gas furnaces which cause the gas to be burned and theburned gas to flow through a vessel having division walls some of whichreach from top to bottom while some reach either not quite to the bottomor not quite to the top. The chambers thereby formed in the interior ofsaid vessel contain water the level of which varies and so provides apassage for the one or the other gas as will be required, said levelbeing controlled from cylinders fitted with pistons having hollow rodsthrough which the water is discharged.

The apparatus is shown in the accompanying drawings, in which:

Figure 1 is a front-elevation partly shown as a section on line AA ofFig. 2. Figs. 2, 3, l, 5 and 6 are sections taken respectively 011 thelines 13-13, CC of Fig. 1, D-D EE and I -F of Fig. 2.

From a pipe a which, for example, conducts away the refrigeratin waterof a Siemens-Martin furnace, two pipes Z) and 0 lead to the vessel d.The latter is divided into a plurality of chambers by means of doublewalls to 0 and contains water of varying levels. The internal walls donot all reach to the bottom such as the walls h and 2', or the top 71;of the vessel as shown by the wall 9. The wall f touches along its fullwidth the bottom of the vessel, its middle portion between the walls Itand 'extends to the top or cover is, while the side portionsbetween thewalls 0, h and 2', m--do not extend so far up. All the walls are hollowand form continuous passages for the refrigerating fluid which the pipes.b and 0 deliver into the external hollow walls 0 and m. Therefrigerating water or fluid is discharged through the pipes 79 and 9which lead into cylinders r and 8. These cylinders are fitted withpistons 1' .9 respectively which have hollow piston rods through whichthe water from the opposite cylinder and from the inner chambers of thevessel d escapes. The pipe u connects the upper space of cylinder 8 withthe lower space of cylinder r and branches off into the chambers II andVII,

The pipe a) connects the lower space of cylinder s with the upper spaceof cylinder 1' and branches off into the chambers III and VI.

Movement is imparted to the pistons by a rocking lever 25 fulcrumed at tand carrying at its ends links Z which are secured to the piston rods ofthe cylinders r and 8 respectively so that the position of the rockinglever directly controls the position of the outlet openings 1' and s ofthe piston rods. The gas enters through the conduit to into the vesselby the chambers VI and VII,

while such gas can be discharged through a chimney flue 2 which connectsthe chambers II and III with the outer air. On each side of the flue eis a furnace flue w or 3 which communicates with the chambers I and IVrespectively.

The reversing action is as follows: \Vith the rocking lever disposed asis shown in Fig. 1, the refrigerating water or fluid passes through thepipe Z2 into the hollow walls 0 and then through the walls f, Z, n andla and through the walls following in communication therewith so that iteventually passes through the pipe p into the space below the piston 7'of the cylinder 7'. The water then ascends the pipe u and also entersthe chambers VII and II from which latter it passes through a bottomspace left by the walls It and 2' and flows into the chambers I and VIIIwhich become filled to a certain level. The water from the pi e 24 alsoenters the upper space of the cy inder s and finally passes through thehollow piston rod to the outlet 8 where it is running away throughsuitable discharge channels. Similarly the second refrigerating currentflows through the pipe 0, through all the hollow walls of the vessel (Z,the down-tube g, the lower space of cylinder 8, the connecting pipe '0and then enters the chambers III, IV, V, VI, which are not traversed bythe first mentioned current, where it ascends to a certain level and atthe same time discharges at 1" through the hollow piston rod of thecylinder 9.

The level of the water in the chambers I II VII and VIII as well as thatin the chambers III, IV, V, VI, will naturally vary according to theposition of the rocking lever t and that of the outlets s and r withreference to the bottom of the vessel d. In the drawings the water levelin the first named chambers is marked .9 and in the last named chambersit is marked t. The gas passes through the pipe w into th'eovessel d andcirculates through the chambers thereof in different directions byreason of the position of the rocking lever and consequent water-levelin said chambers. Vith the position shown in Fig. 1, the gas from theinlet pipe to enters the chambers VI and VII and as the water-level inthe chamber VI is. above the lowest edge of the wall h,

the gas cannot flow away. The chamber VII has its water-level below thewall i and allows the gas to pass into the chamber VIII and then throughthe upper opening in the wall f into chamber IV and thence along thefurnace-flue g into the regenerating furnace. After circulating throughthe latter it flows along the furnace-flue as into the chamber I whereit passes below the wallh into chamber II and then direct into thechimney-flue 2. For altering the direction of the gas-current in thegenerating furnace, the rocking lever t is turned over to the other sideso that the outlet 1' descends while 8 ascends. By reason of theprinciple of level in communicating vessels, the levels in the variouschambers will be reversed from low level to high level and vice versa.The gas from the pipe to can no longer escape from the chamber VII afterthe previously described manner, and now passes from the chamber VIbeneath the wall it into the chamber V, then over the wall f into thechamber I and into the furnacefiue w. The gas therefore circulates in anopposite direction through the furnace which it leaves through thefurnace-flue 2 then enters chamber IV, passes beneath the wall 71 intothe chamber III and escapes direct into the chimney-flue a. By placingthe rocking lever t in a median position the flow of gas is interruptedand the communication between the furnace and the chimney is closed.Therefore while reversing the direction of the gascurrent, no gas mayescape without having passed the furnace. In some instance I maydispense with the hollow walls for single walls and then connect thepipes Z) and 0 direct with the cylinders 1' and 8.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same is to be per formed, I declarethat what I claim is:

1. In a regulating and reversing apparaone piston rod and lowering theother, substantially as described and for the purpose set forth.

2. In a regulating and reversing apparatus for regeneration furnaces,the combination with a vessel, divided into a plurality of chambers,upper and lower openings in the partition walls between said chambers,of conduits supplying gas to said chambers and conducting it away fromthem, of two cylinders having their upper and lower parts connected bypipes, each of said pipes connecting two of the chambers, of hollowpiston rods in said cylinders, having discharge openings for the residueof water, and being connected by a locking lever having links secured tosaidrods and controlling said discharge openings of the oiston rods,substantially as described and for the purpose set forth.

3. In a regulating and reversing apparatus for regeneration furnaces,the combination with a vessel, containing water of varying levels,divided into a plurality of chambers, upper and lower openings in thepartition walls between said chambers, of

conduits supplying gas to said chambers and conducting it through achimney into the atmosphere, of two cylinders having their upper andlower parts connected by pipes, each of said pipes connecting two of thechambers, of hollow piston rods in said cylinders, having dischargeopenings for the residue of water, and of means for simultaneouslyelevating one piston rod and lowering the other, substantially asdescribed and for the purpose set forth.
